Wetbike
A WetBike is a planing water motor cycle that is often described as cross between a motorcycle and a jet ski.
The original Wetbike was introduced in 1978 by Spirit Marine, a subsidiary of Arctic Enterprises (now known as Arctic Cat). The Wetbike is challenging to ride, because it does require a good deal of balance. It was powered by a Suzuki 2 stroke engine, and a small pump-jet.
